Do Black Holes Have to Remain Black?
Summary
This episode explores the theoretical possibility of "colorful" black holes carrying quantum chromodynamic charge. Hosts discuss how primordial black holes formed in the early universe's quark-gluon plasma could have trapped net color charge, potentially influencing dark matter and Big Bang nucleosynthesis. While most would evaporate quickly, near-extremal variants might leave detectable imprints or persist as Planck relics, offering new ways to study the early cosmos.
